Ken Jennings on Wikipedia's lack of authority. I ran into this recently when a vandal changed Aquaman's Wikipedia entry, and an unrelated podcasts read the vandalized entry as if it was true, without any question. If it's on Wikipedia, verify it before you believe it. Wikipedia is a good place to start researching, but it's not to be trusted.

J.L. Bell on piracy. I like it when companies subvert the act of online piracy to their own ends.
